SIPHON-HEAD.

Specification of Letters Patent.

Patented hiar. 7, 1916.

Application filed October 3, 1912. Serial No. 723,696.

To all whom it may concern Be it known that I, JOHN A. SoHUL'rz, Jr., acitizen of the United States, residing at Newark, in the county of Essexand State of New Jersey, have invented certain new and usefulImprovements in Siphon-Heads, of which the following is a specification,reference being had therein to the accompanying drawings, which form apart thereof.

My invention relates to siphon heads, and more particularly to a type ofsiphon head which while being non-corrosive or capable of resisting theaction of the gaseous and fluid contents of a bottle, will containsubstantially no tin or other metal having value as old metal.

The main object of the invention is to provide a siphon head .wherein'the head casing will be composed of two parts, and that portion ofthehead through which the fluid flows will be detachable from said headcasing and adapted to be secured in place by the application of the headto a bottle, and will at the same time lock the two parts of the headcasing in a manner to secure the proper permanent relation of theseparts one to the other.

A further object is .to provide a'siphon head wherein the casing will becomposed of a non-frangible metal havinggreat tensile strength, such asiron, to avoid a stripping of the threads, and wherein the detachablespout portion will be composed of non-metallic material capable of beingworked by tools so as to permit the formation or repair of a valve seatthereon.

A still further object is to provide a siphon head of the characterherein .described, which, while being composed of a plurality ofindependent detachable portions, will when mounted upon a bottle havesuch portions so united as to form a practically integral waterproof andgasproof structure. v

The invention consists in the novel features of construction andcombination of parts hereinafter set forth and described,

and more particularly pointed out in the claims hereto appended.

Referring to the drawings :-Figure 1 is a side elevation of a siphonhead embodying my invention, attached to a bottle; Fig. 2 is a verticalsection thereof; Fig. 3 is a view of the upper portion of the headcasing; Fig. 4 is a detail view of the lower portion of the'head casing;and Fig. 5 is a detail view of the spout and valve seat portlon. v

Like letters refer to like parts throughout the several views.

In the embodiment of my invention shown in the drawings, I have shown ata a cored casing of nonfrangible material having great tensile strength,such as cast iron, the upper portion of this casing being reduced toform a spring chamber a, and the lower portion thereof being enlarged toform a valve seat block chamber a a shouldera being formed within saidlast named chamber adjacent to said first named chamber. Thelower rim ofthis casing a is provided with an outwardly presented flange b. In oneside of, and toward the top of, this casing is formed a slotted way 0for the lever handle, and in the wall of the spring chamber, oppositethis slotted way, is a recess 03 adapted to form a fulcrum seat for saidhandle. The top of the casing is preferably made open, and provided withinterior screw threads adapted to cooperate with the screw threads upona closure cap 6 which may be, and preferably is, made of the samematerial as the casing.

Y Leading from the chamber a is an opening 7' opening downwardly throughthe flange .b, the upper portion of this opening being adapted toconform to the contour of the spout. WVith a round spout, the upper endof this opening willbe curved as shown in Fig. 3 of the drawings.

The lower portiong of the head casing is preferably composed of the samematerial as the portion a and is circular in form, and provided adjacentto the lower edge thereof with interior screw threads g adapted tocooperate with the split ring In commonly used for attaching the siphonhead to. a bottle, indicated at i. The top of this portion g is providedwith a circumferential, inwardly projectedflange y' adapted to bear uponthe-flange b .ofthe head portion 0;. Through one wall of said portion 9adja cent to the top thereof is an opening 9 adapted to register withthe lower. portion of the opening 7 and confine the spout between thesetwo p arts.

Seatedwithin the chamber a is a valve seat block k having connectedtherewith, preferably integrally, a spout is This spring spout is soformed-as to have a fairly close sliding fit with the opening 9 thusserving, when the head is assembled, to prevent the rotation of one ofthe parts a or is relative to the other. To permit the insertion of thisblock within the bi-part head casing I make it in the form of atruncated cone, the top dimension of which is the smaller. Seatedbetween the top of the block A; and the shoulder a is a packing ring Zwhich serves to prevent the escape of any of the fluid contents of thebottle about the valve stem.

Extending vertically through the block it is a port and moving in thisport is a pressed valve spindle m having an enlarged head m terminatingadjacent to the slot 0 and recess 0?. Acting between the ring or gasketZ and this enlarged head is a spring m having a normal tendency to raisethe spindle. Acting upon said enlarged head is an ordinary lever handlem moving in the slot 0 and having the inner end thereof seated withinthe recess d.

The upper face of the block is is recessed as shown atlc to insure theexpansion of the gasket Z toward the valve stem m. Centrally of thelower face of the block it and extending about the lower face of theport 70 is a continuous circular valve seat n which projects to aconsiderable extent from the lower end of the block is. Encircling thisvalve seat is a channel 0 forming an annular shoulder 32 about the seat12. adapted to engage the flange of the metallic siphon tube head (1.Adjacent to the spout lo I provide a segmental bead 7- adapted to fitthe open space in the rim 7' at the opening 9 thus when'the device isassembled, presenting a substantially continuous bead within the section5/ against which the gaskets which is used for sealing the entire valveblock is, the siphon tube head q, and the section a, may bear in amanner to prevent the escape of water therefrom. Carried by the lowerend of the stem m and seating on the Valve seat n is the customary valveblock 6.

Preferably the valve block is and the spout is. are formed of nonmetallic material such as vulcanite, indurated fiber, or other similarmaterial, which may be molded to form,

and yet be capable of being worked with tools. The materials named aresubstantially water, acid and gas proof, permitting the production ofthe entire head at a reasonable cost, and at the same time eliminatingfrom the head any metal having value as old metal. If desired, tin maybe used for the valve seat block and spout without departing from thespirit and scope of the invention, but I prefer to use the othermaterials. When I use the vlucanite or indurated fiber, I provide thetop of the port 76 with a metallic bushing is in which the stem m moves.

The operation of my head when assembled is substantially like that ofany other head of the ordinary type, as to the charging and dischargingof the fluid contents of the bottle. In assembling the device, however,the bi-part construction of the head casing permits such a relativemovement of parts as will facilitate the insertion of the valve seatblock and spout, these parts, however, being so united when pressure isapplied upon the part 9 by the split ring it, as to give such rigidityto the entire structure that it will to all intents and purposes, be aunitary structure when assembled upon the bottle. The gasketsiscompressed upon the lip of the bottle 2' by the pressure exerted by theannular shoulder 9, upon the flange of the siphon tube head 9, theportion of the said gasket projecting beyond this flange being slightlycompressed by the flange b and fitting 1" so as to seal the jointbetween the two sections a 9. As heretofore stated, the spout 7c havinga close slidingfit with the openings 7 and 9 the parts a g are held insuch relation to each other as to prevent any such movement of eitherpart as would result in wear upon the gasket 8. The block 70 is made inthe form of a truncated cone in order to afford suflicient clearancebetween the upper part of the block it and the wall of the chamber (E,in assembling the device.

WVhen mounting the head upon a bottle, the split ring 71 will exert adownward pull upon thepart g, and cause this part through the flange jthereon to. exert sufficient pressure upon the part a through the flangeb thereon, to compress both gaskets Z and s and thus firmly seat theblock it within the chamber a If by any chance there should be animperfection in the annular shoulder 39, the gasket 8 will pack theflange b and bead r in a manner to prevent the escape of the fluid.

. Having described my invention, what I claim as new and desire to haveprotected by Letters Patent, is

1. A siphon head embodying therein a bipart head casing, the lower partof which has interior screw threads, an opening in the top thereof, arecess in one side wall thereof opening into said top opening and aninwardly projected flange about the opening in the top thereof exceptingacross said recess, and the upper of which parts has an open bottom, areduced portion forming a spring chamber, an enlarged bottom portionforming a valve block chamber, aspout opening in the side wall thereof,and an outwardlv projected flange extending about the open bottom ofsaid part excepting across said spout opening, said flange being adaptedto engage the flange of said first named part whereby separation of saidparts when assembled is prevented, said spout opening being adapted toregister with the recess in said first named part, a valve block adaptedto be seated in said valve block chamber, a spout carried by said blockand adapted to project through and engage the sides of said spoutopening and the recess in said parts respectively, said valve blockhaving a bead thereon adjacent said spout whereby said bead and theflange about the bottom of said valve block chamber will form asubstantially continuous rim adapted to engage a gasket, and a Valvemechanism.

2. In a siphon head the combination with a bi-part head casing, one ofthe parts of which has internal screw threads, an opening in the topthereof a recess in one side wall thereof opening into said top opening,and an inwardly projecting flange about the opening in the top thereofand the other part of which has an open bottom, a reduced Copies of thispatent may be obtained for five cents each, by addressing theCommissioner of Patents,

a spout integral with said block adapted to,

project through and engage the sides of the spout openings in both partsof the head, and a valve mechanism.

In witness whereof, I have hereunto affixed my signature, in thepresence of two subscribing witnesses, this 16th day of September, 1912.
